Cycles: Allow negative values in Combine XYZ node.

Event System Cleanup: Modifier Key Assignment Switch

Was quite messy previously, think this is much more readable and easier to follow.

Submodules: Make them pointing to the master branch

Otherwise it gives all sort of weird and wonderful artifacts.

Fix T40435: Fix event system modifier key handling

This partial reverts rBd800cffaf10cb7, but fixes T40435 (Background label is not
redrawn).

It now isn't possible to use single modifier keys as shortcuts anymore. But this
is something that's not really useful at all, since it breaks more than it allows.

Remove slurph shape-key feature

This is an old option which wasn't working in over a year without complaint.

Fix copy-paste of colors to generated color not being correct. '

Change generated color property to gamma space to match the add new
image operator.

Logic Bricks *must* be kept in alphabetical order

Fix T43137: vertex bevel percent mode wasn't implemented.

Point submodules ot latest release tags

Sequencer: show extensions when preview enabled

Expose viewer panels also when backdrop is active. Allows to select
proxy size, render type etc.

Cycles: Repot CPU and CUDA capabilities to system info operator

For CPU it gives available instructions set (SSE, AVX and so).

For GPU CUDA it reports most of the attribute values returned by
cuDeviceGetAttribute(). Ideally we need to only use set of those
which are driver-specific (so we don't clutter system info with
values which we can get from GPU specifications and be sure they
stay the same because driver can't affect on them).

Fix T43143: DPX header wrong, making it impossible to import to other software

The issue was caused by the single letter in header, which is expected to be
captial as per standard: http://www.simplesystems.org/users/bfriesen/dpx/S268M_Revised.pdf

cleanup: warnings

Correct args from recent mathutils refactor

PyAPI: add PyList_APPEND

This appends while giving ownership to the list, avoiding temp assignment.
This matches PyList_SET_ITEM which bypasses refcount's

Note, this also reduce code-size, Py_DECREF is a rather heavy macro.

PyAPI: add utilities PyTuple_SET_ITEMS, Py_INCREF_RET

Setting all values of a tuple is such a common operation that it deserves its own macro.
Also added Py_INCREF_RET to avoid confusing use of comma operator.

BGE: Fix for bugs T42520 and T42097 (mouse look actuator related).

With this fix the mouse actuator movement works well as with even screen resolutions as odd screen resolutions.
Also it fixed the movement when the border of the blenderplayer window is out of the screen limits.
